Haha a common problem with the rock throw. The times I’ve successfully pulled this off, they were either very close to me when I nailed them with the rock, or I was on top of a cliff (giving me longer range for the Leap Smash).

Don’t really have any combos best I’ve pulled off was leaving a direct track to the exit of a cave and placing banshee mines around the outside and using lighting strike the moment the mines start screeching. They also try to dodge the strike and ignore the mines only to get hit by both.

As Goliath, leap smashing a hunter into a wall, then proceeding to use rock throw on him, beating him to death with it.
This is why I don’t understand why people say you have to kill the medic first, they can only heal the hunter while said hunter is alive.
